Hi all, I have just released the second alpha snapshot of what will become Samba 2.2.0. It's available from the usual ftp sites, in the alpha directory as : <ftp mirror>:/pub/samba/alpha/samba-2.2.0-alpha1.tar.gz If people could test this snapshot out and provide feedback about what is broken (probably lots at the moment :-) and let the lists know that would help. The Team will be monitoring the feedback and this will help for the next alpha. Please note that the documentation is not currently up to date, and the POSIX ACL mapping feature is still missing, but most of the other improvements are all there, and this code has been running under memory overrun/leak detectors for weeks now without problems. Having said that - *please* don't use this on a production system :-) :-). I believe that most of the patches people requested have been added to this release, and that the NT point and print code is much more robust than alpha0. Jean-Francois patches for Win2K PDC support have also been included. Please kick the tires and let us know what you think ! The release notes follow : Regards, Jeremy Allison, Samba Team. WHATS NEW IN Samba 2.2.0alpha1 ============================= This is the second alpha release of the new 2.2.0 codebase for Samba. This version must not be run in production. This code will almost certainly have some bugs and is intended to help the Samba Team prepare an official 2.2.0 release. The documentation in this alpha snapshot is not up to date, there are many new parameters since 2.0.7. This will be corrected in a later alpha release. Several significant bugs have been fixed between alpha0 and alpha1, these include : Fix for level II oplock bug. Support for detecting version 2/3 printer drivers (from HP). Samba profiling support (from SGI). Winbind integration fixes. Preliminary Win2K PDC support in compatibility mode for Win2K clients (from JF). VFS interface updates. Failover finding of BDC's now works again. lpq race condition fixes. utmp fixes. SWAT username detection fix. Bugfix for WinNT and Win2K point and print feature. The upcoming 2.2.0 Samba release will include the following new features: Integration with the winbind daemon that provides a single sign on facility for UNIX servers in Windows NT4/2000 networks driven by a Windows NT4/2000 PDC. Support for native Windows NT4/2000 printing RPCs. This includes support for automatic printer driver download. This functionality should be complete in alpha1. Rewritten internal locking semantics for more robustness. This alpha supports full 64 bit locking semantics on all (even 32 bit) platforms. SMB locks are mapped onto POSIX locks (32 bit or 64 bit) as the underlying system allows. Conversion of various internal flat data structures to use database records for increased performance and flexibility. Support for acting as a MS-DFS server Compile time option for enabling a VFS layer Support for server supported Access Control Lists (ACLs). This support will require a specific pluggable backend to be written for each filesystem ACL implementation to be supported. The stable 2.2.0 release should contain support for the following filesystems: Solaris 2.6+ HPUX SGI Irix Linux Kernel 2.2 with German ACL patch Currently in this alpha snapshot (alpha1) this feature is not enabled - the VFS layer has been modified to allow it, but the code is still under development and should be in a later alpha snapshot. Other platforms will be supported as resources are available to test and implement the encessary modules. If you are interested in writing the support for a particular ACL filesystem, please join the samba-technical mailing list and coordinate your efforts. Support for collection of profile information. A shared memory area has been created which contains counters for the number of calls to and the amount of time spent in various system calls and smb transactions. See the file profile.h for a complete listing of the information collected. Sample code for a samba pmda (collection agent for Performance Co-Pilot) has been included in the pcp directory. To enable the profile data collection code in samba, you must compile samba with profile support (run configure with the --with-profile option). On startup, collection of data is disabled. To begin collecting data use the smbcontrol program to turn on profiling (see the smbcontrol man page). Profile information collection can be enabled for all smbd processes or one or more selected processes. The profiling data collected is the aggragate for all processes that have profiling enabled. With samba compiled for profile data collection, you may see a very slight degradation in performance even with profiling collection turned off. On initial tests with NetBench on an SGI Origin 200 server, this degradation was not measureable with profile collection off compared to no profile collection compiled into samba. With count profile collection enabled on all clients, the degradation was less than 2%. With full profile collection enabled on all clients, the degradation was about 8.5%. ==================================================================== If you think you have found a bug please email a report to : samba@samba.org As always, all bugs are our responsibility.

I'm still seeing a problem that I've had with the CVS releases in general. Under 2.07, I'm running Samba as a domain member of a NT 4 domain. When somone connects, it looks like Samba checks their creds against the domain controller only. Under 2.2.0, with same /etc/smb.conf, it immediately goes to /etc/smbpasswd - which I have never had! So auth fails, yada, yada, yada... If I put a valid smbpasswd file there, then it works - but the whole point is to auth off existing NT domain controllers... This is under RedHat 6.2 [global] workgroup = TNZ server string = Samba Server %v security = DOMAIN encrypt passwords = Yes update encrypted = Yes password server = PDC BDC unix password sync = Yes log level = 9 log file = /var/log/samba/log.%m max log size = 0 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 lm announce = False local master = No dns proxy = No wins server = PDC guest account = smbguest -- Cheers Jason Haar Unix/Special Projects, Trimble NZ Phone: +64 3 9635 377 Fax: +64 3 9635 417
IRIX 6.x inst packages available on main samba site (and mirrors soon).

Are you sure your not running some old (rpm installed) binary or config file somewhere ? Have you used the samba default (and very sensible) file locations /usr/local/samba/* ? david ------------------------------------------------------------ David Bannon D.Bannon@latrobe.edu.au School of Biochemistry Phone 61 03 9479 2197 La Trobe University, Plenty Rd, Fax 61 03 9479 2467 Bundoora, Vic, Australia, 3083 http://bioserve.latrobe.edu.au ------------------------------------------------------------ .....

Hi all, I have just released the third alpha snapshot of what will become Samba 2.2.0. It's available from the usual ftp sites, in the alpha directory as : <ftp mirror>:/pub/samba/alpha/samba-2.2.0-alpha2.tar.gz If people could test this snapshot out and provide feedback about what is broken and let the lists know that would help. I know about the problem acting as a PDC for Win2k clients - this is being worked on (by JF and myself). The Team will be monitoring the feedback and this will help for the next alpha. The POSIX ACL mapping feature has been implemented on Linux only at the moment and many bugs in the point and print code have been fixed. The documentation is not currently up to date, but this code has been running under memory overrun/leak detectors for weeks now without problems. Having said that - *please* don't use this on a production system (yet - although it's closer now.... :-). I know there are still some patches missing, I will try and get to these as soon as I return from the Linuxworld conferences and the Brussels Open Source conference (Feb 8th). Please kick the tires again and let us know what you think ! The release notes follow : Regards, Jeremy Allison, Samba Team. ==================================================================== WHATS NEW IN Samba 2.2.0alpha2 ============================= This is the third alpha release of the new 2.2.0 codebase for Samba. This version must not be run in production. This code will almost certainly have some bugs and is intended to help the Samba Team prepare an official 2.2.0 release. The documentation in this alpha snapshot is not up to date, there are many new parameters since 2.0.7 and some defaults have changed. This will be corrected in a later alpha release. A known problem is this version of Samba will not act as a PDC for Win2k clients (although it works as a member server in a Win2k hosted domain). This is being actively worked on and it is intended this be fixed before 2.2.0 release. Several significant bugs have been fixed between alpha2 and alpha2, these include : Inclusion of mapping of NT ACLs to Linux ACLs, using the patch found at http://acl.bestbits.at. This is being done via an abstract interface that needs porting to the following UNIXes - IRIX, Solaris, HPUX, AIX - as many as can be done will be supported at 2.2.0 release. Please look at the code in lib/sysacls.c for the needed work. Addition of tdb spinlock code for tdb speed. Addition of user list lookup from Win2k (thanks to the Samba TNG branch code for this). Addition of generic to specific mapping of security descriptors in printer code. Addition of code page 857 (Turkish). Addition of "%D" substitution for incoming Domain of user. getpwnam/getpwuid cache. Many codepage fixes when dealing with printers with extended characters (thanks to HP for this fix). Inherited security descriptors for printing. Creation of internal NT "token" for smbd access checks. Addition of NT trans code for client. Fix for inheritance of blocked signals (thanks to HP). Addition of "total print jobs" parameter. Fix for NT not being able to save properties changes on PCL drivers. Fixes to speed up enumeration of print jobs. Cleanup printer spool files on client disconnect. Byteswap fixes for printing code (thanks JF). New parameter "dos filemode" to allow a user who can write to a file to change permissions on it. Subtle statcache bugfix. Fix for Office2000 print to file bug. Fix for MS Access multi-user open problem. Valid users now in linked list rather than array. SMB lookup now table driven rather than linear search (doh!). TDB locking fixes for multiple openers. Several significant bugs have been fixed between alpha0 and alpha1, these include : Fix for level II oplock bug. Support for detecting version 2/3 printer drivers (from HP).
